What happened

The episode as NWS PHI wrote it up.

The combination of a low pressure system approaching from the Carolinas and a frontal system approaching from the Midwest spread precipitation across northwest New Jersey overnight on the 11th into the 12th. While it was warm enough for precipitation aloft to fall as rain, temperatures at the surface were still below freezing, especially in the higher terrain. The freezing rain made driving hazardous and resulted in accidents. Accidents were reported on New Jersey State Route 94 in Blairstown (Warren County). Temperatures continued to rise overnight on the 11th and by 6 a.m EST on the 12th most of northwest New Jersey's temperatures had risen above freezing. Ice accretions were generally less than one tenth of an inch.
